Three Islamic State fighters were mauled to death by a pack of wild boar, reports U.K.’s The Times. Another 5 militants were also injured in the attack.

The men were said to be taking cover in a field as they set up an ambush for local tribesmen, local leaders said.

“It is likely their movement disturbed a herd of wild pigs, which inhabit the area as well as the nearby cornfields,” Sheikh Anwar al-Assi, a chief of the local Ubaid tribe and supervisor of anti-ISIS forces, told the Times. “The area is dense with reeds, which are good for hiding in.”
